How to Fix CVE-2026-45222

To remediate this vulnerability, upgrade all affected @steipete/summarize dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@steipete/summarize fixed: 0.15.0 
npm install @steipete/summarize@0.15.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @steipete/summarize

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-45222, inspect your project dependencies using npm:

npm ls @steipete/summarize

Analyze the terminal output to locate any version of @steipete/summarize in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.15.0), your application is affected.

Note: The npm ls @steipete/summarize command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-732: Incorrect Permission Assignment for Critical Resource, where the product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors. In @steipete/summarize, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Summarize versions through 0.14.1, fixed in commit 0cfb0fb, creates the daemon configuration directory and file with default filesystem permissions that may be world-readable on Unix-like systems, allowing local attackers to read bearer tokens and API credentials stored in ~/.summarize/daemon.json. A local attacker can exploit these permissive permissions to read the daemon bearer token and persisted provider credentials, enabling unauthorized access to the daemon or recovery of sensitive API keys.
